不同土层对氟离子的吸附能力不同，在吸附能力较弱的土层建设贮灰场，会导致周边地下水中氟离子质量浓度较高，污染地下水。吉林市来发屯灰场运行多年来，地下水中氟离子质量浓度与背景环境未见明显差异，本文通过对来发屯灰场粉煤灰-粉质粘土和灰场外土层的比较分析，探究吸附机理，结果表明：粉煤灰-粉质粘土对氟离子有较强的吸附能力，能有效防止其对地下水的污染。

Previous studies showed that the adsorption capacity of different soil layers on the lfuoride ion are different, to build ash storage ifeld in soil layers where weak adsorption capacity, will lead to the high mass concentratrion of F-in surrounding groundwater, thereby polluting groundwater. Jilin Laifatun ash yard is used for years, groundwater F-mass concentratrion has no signiifcant difference with the background environment. In this paper, through comparative analysis of lfy ash-silty clay in Laifatun ash yard and soil layer outside, to explore the adsorption mechanism. The results showed that lfy ash-silty clay has a strong adsorption capacity on F-, can effectively prevent pollution of groundwater.
